I don't know how a limit switch works, per se, but I understand that in this context, once the motor reaches a certain point, it stops the motor from spinning any further and over-tightening/loosening the arm. I have built a circuit that handles my automation, but these linear actuators (Zoom Industrial Z1000WH) have built in limit switches that I'd like to modify to perfect my driveway gate setup. I installed it with the gate closed to make sure it closes the way I want, but when it opens, it simply opens way too far and it occurred to me that if I can modify the limit switch (I assume there are two switches, one for extending and one for retracting movements) that I can get it to work exactly how I want it to. Is this a feasible pursuit?
